MCQ
Why is there a sudden increase in current in Zener diode ?
- ✓due to rupture of bonds
- Bresistance of depletion layer becomes less
- Cdue to high doping
- Dnone of the above
✓
Answer
Correct option: A.
due to rupture of bonds
a
When Zener diode is connected in reverse bias, as applied voltage reaches at Zener breakdown voltage, due to rupture of bonds there is a sudden increase in current in Zener diode.
